Specification of Letters Patent.

- Application filed September 14, 1909. Serial No. 517,561.

treating lumber with a preserving fluid, and

more. particularly to apparatus by which sections of pieces of lumber may be treated without treating the entire lengths of the lumber, and the object is to provide apparatus for treatin lumber which is adapted to treat the whoe pieces of'lumber or any length of the pieces of lumber, and particularly to treat the butt end sectionsofsuch poles as are adapted for telegraph and telephone lines and electric light lines,,and similar poles.

Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims. A i Reference is bad to the. accompanying drawings which form a part of this. application and specification.

Figure 1 is a side elevation of the apparatus constituting my invention. Fig. 2 is a detail view of the treating cylinder or chamber, showing one end cap detached. Fig. 3 is an end elevation of the tram, can track, showing the manner of supporting the end of the treating cylinder. Fi .4 is a broken view of the track, being a si e elevation of a portion of the track and showing the manner of supporting the end of the treating cylinder. Fig. 5 is a cross-section of the treating cylinder and showing the means for turning the cylinder on the supporting trunnions. Fig. 6 illustrates a variation in the means for changing the position of the treating chamber.

Similar characters of reference are used to indicate the same parts throughout the several views.

A cylinder 1 is chamber. The cyllnder is provided with end caps 2 and bolts 3 and nuts 4 by which the cylinder may be hermetically sealed as such cylinders areusually sealed. The cylinder has a pipe connection 5 and valve 6 for compressed air or other purposes and a pipe connection 7 and valve 8 for admission of a preserving fluid. The cylinder is also 'may be applied to the provided for a treating" provided with a drain pipe connection 9 and valve 10. The pipe 5 may be connected with any supply source of compressed air so that pneumatlc or hydraulic pressure may be applied to the contents of the cylinder, but the plpe connection 5 must be far enough from one end of the cylinder so that the pipe connection will not be below the surface of the preserving fluid within the cylinder when the cylinder is turned to vertical position. The pipe 8 maybe connected to any suitable supply source of preservative fluid.

The cylinder can thus be used to carry out the burnettizing processor creosoting process pr other process of treatin lumber. The cylinder is further adapte for treating the buttends of poles or sections of lumber. The cylinder may be made to any'suitable size, the cylinder for general purposes being preferably forty feet long and six feet in diameter. The cylinder is pivotally mounted on trunnions l1 and 12 which have bases 13 which may be riveted to or formed integral with the cylinder 1. Bearings 14 are provided for thetrunnions 11 and 12 Bearin blocks 15 are mounted on frames 16 and bo ted thereto by bolts 17. The frames'16 tn-e preferably about twenty feet hi h for a forty feet cylinder and frames of different heights will be necessary for cylinders of different lengths. The frames 16 may be braced in any suitable manner.

.Means are provided for turning the cylinder 1 its trunnions. A gear wheel'or cog wheel 18 is mounted on the trunnion l1 and attached rigidly to the cylinder 1 by cleats 19 whichare riveted to the cylinder.

A pinion 20 meshing with cog wheel- 18 is mounted on a shaft 21 which is journalpd in bearings 22 and 23. A fast pulley 2 2' for driving the gearing 20 and 18 is mounted on the shaft 21 and a loose pulley 25 is also mounted on shaft 21. Any suitable power pulley 24 to position the cylinder 1. The cylinder may be horizontally disposed or vertically disposed at will. On account of the reat length of the cylinder, braces 2.6 may .e attached to the exterior of the cylinder and provided with a turnbuckle 27 for adjusting the braces to the cylinder.

Means are provided for loading and unloading a cylinder. Tram cars 28 for hauling the lumber or poles are prov1ded A track 29 may be rovided for entering either end of the cylin er. The tram cars are run Patented Apr. 26, 19 10. 1

29. These supports are pro 'from the track 29 into the cylinder on tracks 30. Means are provided for holding the cars 28 on the tracks 30. The tracks 30 are provided with flanges 31 and lugs 32 are attached to the cars 28 so that the lugs will project under the flanges 31 as the cars move. With this construction, the cars will not leave the track'when the cylinder is ver- The lumber may beheld on the cars by suitable chains 33 or equivalent means.

Means are provided for supporting the cylinder against movement while in a horizontal position. Supports 34 are slidably mounted on the beams 35 under the tracks 'ded with lugs or handles 36 which project through slots in, the beams 35. The supports 34 may be moved by the handles 36 and brought under the ends of the cylinder to support the same and the handles may be used to remove the supports when not in use. The end caps 2 are preferably made flat on the interior so that all the poles will'reston a level surface and be even.

any of the preserving fluids or to carry out numerous processes similar to the creosoting' or the burnettizing' process and that the cylinder can be maintained in a horizontal po: sition forlthis purpose. It is also apparent thatthe sai cylinder can be vertically disposed so th t any suitable or desirable portion of pieces of'lumber may be treated with a preserving fluid. The apparatus is also adapted to carry out the ob ect of this inthe treatment of the butt ends or sections of poles.

The lumber is loaded on the tram cars and secured thereto by suitable binding means. The tram cars are then ready to be placed in By means of the gearing the cylinder is brought. to a horizontal position on a line with the terminals of'the tracks and the supports 34 are placed under the ends of the cylinder. The car of poles or lumber is then run into the cylinder. The cylinder maythen be hermetically sealed. By means of the gearing described, the cylinder'is brought to a vertical position. In case of poles, the end' of the cylinder which contains the butt ends of poles is lowered next to thedground. Creosote or other preserving flui is then let into the cylinder up to the desired height, and maintained at such height during the treatment of a charge of poles.v It is a parent that such cylinder be heated y-coils of pipe 40 as other cylinders are heated. Compressed alr may 'be forced through the pipe 5 and hydraulic pressure used to force the liquid preservative into the sections-of the wood. After the oles have been sufiiciently treated, the cylinder can be brought back to the horizontal ative to its pivotal mounting.

position by suitable gearing. The preservmg fluid not forced into the lumber mabe drawn ofi before changing the cylinder fi'om the vertical position. back to horizontal position the'cylinder is unsealed and one end removed so that the After .being broughtcharge of timber may be moved out of the cylinder.

Besides the means for locking the cylinder 1 in a horizontal osition by the supports heretofore describe it is ap' arent that the gearing for turning the 'cy inder ma be locked at any position so that the cham er 1 may be locked in any desirable keeper 42 is attached to block 15 and a locking bolt 41 is slidably mounted in the kee er 42. The locking bolt may be moved by a ob or handle 43 which moves in a slot m the keeper 42, the knob being attached to the bolt 41. The lockin bolt 41 may be made to cog w eel 18 at any part there etween two cogs and thus .lock the wheel against rotation. Gearing shown inUFig. 6 may be used for changing the position of the cylinder. A chain or cable 37 with sheave wheel 38 and Windlass 39 may be used for moving the cylinder.
